Chapter 2 Vocab
|Amount of energy deposited in any form of matter, by any type of radiation.
|Ionizing radiation always present in the environment.
|Produced when an electron from the tube filament connects with an orbiting electron.
|Low energy x-ray passes near an atoms outer electron, which results in a scatter but no loss of energy.
|Dental x-ray interacts with an orbital electron, and the x-ray energy is transferred to the electron.
|Happens when an unstable isotope tries to regain stability by releasing energy.
|When the radiation is absorbed into the tissues.
|Used for radiation protection to compare the biological effects to various radiation. Absorbed dose x biological effect.
|Effective Dose Equivalent
|Used to compare the risk of the radiation exposure producing a biological response.
|Movement of wavelike energy through space as a combination of electric and magnetic fields.
|The measurement of ionization in air produced by x-rays.
|Measurement of waves that pass a given point per unit of time.
|(Gy). Unit for measuring absorbed dose.
|Radiation with great penetrating power.
|Is the formation of ion pairs.
|Radiation that produces ions.
|Bundles of energy that travel at the speed of light.
|Radiation Absorbed Dose
|Emission and movement of energy through space.
|X-rays appear dark gray or black.
|X-rays appear white or light gray.
|Unit for measuring dose equivalent.
|(R). Unit for measuring exposure.
|Travels the opposite direction of original x-ray.
|(Sv). SI unit for measuring dose equivalent.
|Limited penetrating power and unsuitable for exposing dental radiographs.
|The distance between two crests on a wave.
